Question

A. Estimate the molar solubility of magnesium phosphate Mg3(PO4)2 in pure water at 25 °C assuming the dissolution of is the only equilibrium taking place in solution. (Ksp = 1.04×10^-24 for Mg3(PO4)2 at 25 °C) (enter your answer to two decimal places in scientific notation omitting the unit. e. g. enter 1.47E-10 for 1.473×10^-10) B. State whether the solubility increases, decreases or remains the same when an aqueous solution of Mg(ClO4)2 is added to a saturated solution of Mg3(PO4)2 at 25 °C. (enter + for increase, - for decrease and = for same) C. State whether the solubility increases, decreases or remains the same when an aqueous solution of HCl is added to a saturated solution of Mg3(PO4)2 at 25 °C. (enter + for increase, - for decrease and = for same) D. Will a precipitate form when 25 mL of 0.025 M Mg(NO3)2 aqueous solution is mixed to 25 mL of 0.015 M of Na3PO4 aqueous solution? (Yes/No)
